Really, I am imagining much larger games than standard.
Like entire collections facing each other at once sort of thing.
1500-2000 points per side.
EPIC scale
I was thinking about getting a second damage deck and shuffling them together.

Will the SSD come with it's own damage deck? There are only 52 cards in the base Armada damage deck and you'd need 32 of them applied to just the SSD in order to bring it down. Seems like the game could be starved of cards.
The super over-sized ship card: any idea on sleeves? I doubt that is a standard card size.

Why did they print the specific name of the single seat variant on all cards?
The BTL-A4 is a one-seater, notably flown by Dutch Vander and Gold Squadron.
The BTL-S3 (like the Clones Wars era BTL-B before it) was a two seater, notably flown by Horton Salm and Gray Squadron. The best pilot/gunner pair might be Wes Jason and Hobbie Klivian.
The S3 variant was Legends, of course, but now is Canon again, thanks to multiple recent Disney-era mentions: The Weapon of a Jedi Luke Skywalker book and the Poe Dameron comics (starting with issue 17).
I assume in 2.0 you can have a gunner (or other crew member?) added to the "BTL-A4", which makes no sense. Seems like a typo-level error.
Ideally we'd have two sets of Rebel Y-wing pilots cards: BTL-A4 for the Gold Squadron guys and BTL-S3 for the Gray Squadron guys.
It seems like the second time FFG has screwed up with the Y-wing.
On the plus side, the new model looks great!

Oddities from Rebel Conversion Kit.
Where's *Thane Kyrell (T-65), *Evaan Verlaine (Y-wing), and *Norra Wexley (Y-wing) in the official contents list?
For the unique pilots of the ARC-170, Phantom I, Phantom II, Sabine's TIE: each pilot can only fly next to 2 of the 3 other pilots, using just the contents of just 1 kit.
YT-2400 can fly with 2 generics; Falcon, Ghost, U-wing cannot.

I see that the "Quick Start" cards from Core 2.0 are showing *Luke & Red Squadron Vet and *Porkins & Blue Squadron Escort.
Thus, the Core 2.0 should provide 4 pilot cards for T-65 along with 2 base tokens:
*Luke Skywalker/Blue Squadron Escort
*Jek Porkins/Red Squadron Veteran
EDIT: To be fair, these might be swapped. The only way to get 2 X-wings from a Core 2.0 set is to have 2 Core 2.0 sets. Thus a double up of tokens (i.e. using unique Luke face-up and unique Luke face-down; i.e. Red Squadron Veteran; would work just fine.
